HOPPER GAR DOOR-.

To all whom it may concern Be it known that I, CARL M.- LUTH,2& c1t1 zenof. the United lVilkinsburg,-, in the county and State of Pennsylvania,

is a specification.

This invention relates to hopper cars and while not limited theretorelates more parto self propelled ore transfer hopper cars, such as usedto transfer ore and other materials from stock piles to bins, and thelike, at steel mills and manufacturing plants.

The principal object of the present lnvention is to provide a novel formof closure for the hoppers of this class of cars, which willautomatically thus preventing spillage, as is common with heretoforeused.

Another object is to provide a novel .form of hopper car of the classdescribed, having the novel design, construction and combination ofparts hereinafter described and illustrated in the accompanyingdrawings.

Heretofore hopper cars have been formed with their hinged sides or doorsadapted to "close, forming a butt joint and if, as is often the case,any of the material being hauled would adhere at points along the loweredge of the doors, the doors would not close tight- 1y together, butremain spaced sufliciently to permit spillage along the whole path oftravel. Also tofore, when the load was put in the car they would springslightly open, even if they were tightly closed, before the load wasdeposited, thus permitting spillage.

All of these disadvantages are overcome with cars constructed inaccordance with this invention, and spillage is prevented.

In the drawings, Figure l is a top plan of a car constructed inaccordance with this invention. 7

Figure 2 is a side elevation thereof.

Figure 3 is an enlarged cross sectional elevation on the line III-III ofFigure 2 Referring more particularly to the draw ings, the numeral 2designates the wheeled trucks of the car supporting the sill portion 3,upon which is secured the side walls 4 and 5, end walls 6 and 7 andfront and rear cabs 8 and 9.

The car is divided intermediate its ends States, and resident E of i of:Allegheny; have invented certain new and useful Improvements inHopper-Car Doors, of which the following,-

form a seal when closed.

with the doors formed as herescribed, it will b by transverse wall orpartition. 10 into two i Y longitudinally extending. hopper 1 portionsAandrB) The sidewalls 4 andf5 and. end

walls 6 and 7and walls of partition-'10 are inclined inwardly anddownwardly to faf+ .cilitate: the movement of the. material car riedbythe car .tl'izroughthe hoppers:

Thehopper. portions A andiB :eachwhave :their bottom adapted to;beiclosedby in- 1 doors 12..and 1 1 hinged alohgtheir clined upper edgeto the sides of the car body..

The door 12 of each hopper is provided with a longitudinally extendinggroove adjacent its lower edge, which groove is provided with beveled oroutwardly flaring side walls and a fiat bottom, and the door 14 of eachhopper is provided with alongitudinally extending lip or projection 16having its lower edge beveled to correspond with the lower inclined orbeveled side face of the V-shaped groove 15 in the door 12. The lip 16of the door 14 is adapted to enter and form a sealing connection orjoint with the groove 15 of the door 12. when said doors are closed. Thelower sides of the groove 15 and the lip 16 being substantiallyparallel. It will be readily seen that with doors constructed inaccordance with this invention they may spring a limited amount, due tothe depositing of the load without opening a passage through which theloaded material will spill, and, further, if particles of the materialshould stick onto the doors when being discharged, such material, due tothe novel form of the groove 15 and lip 16 and the position they assumeupon closing, will be pushed upwardly into the hopper and not interferewith the complete closing of the doors.

While only one specific embodiment of the invention has been illustratedand dee understood a that various modifications may readily be madewithout departing from the scope of the invention as defined in theappended claims.

I claim l. A hopper car having the hoppers extending longitudinallythereof, and the bot-' tom of said hoppers being closed by inclinedhinged doors, one of said doors being provided with a longitudinallyextending groove on its inner faceadjacent its lower edge, said groovehaving beveled side walls and a flat bottom face, and the other of saiddoors being provided with a projecting lip All along its lower edge,said lip being provided with a beveled lower edge and being adapted toproject into said groove. when said car having a plurality oflongitudinally extending hoppers, each of said hoppers having theirbottom closed by inclined hinged 1 doors, said doors being hinged alongtheir upper edges'to the body or" said ear, one of said doors beingprovided with a longitudin ally extending groove on its inner faceadjacent its bottom edge, said groove having outwardly flaring-sidewalls, and the other of said doors being-provided with a projecting lipalong its lower edge, said lip being provided with a beveled loweredgeand beingadapted to project into said groove,so

thatsaid beveled lower edge of said lip will i signed my name,

form a sealing connection with the lower side wall of said groove. i

3. A'hopper oar having a plurality of hoppers, each of said hoppershaving their bottom closed by inclined hinged doors, said doors beinghinged along their upper edges to the body of said car, oneof said doorsbeing provided with a longitudinally extending'groove on its inner faceadjacent its lower edge, said groove having beveled side walls and aflat bottom of saiddoors'beingprovided with a project- 'inglip along itslower edge, said lip being provided with a beveled lower edge and beingadapted to project into said groove when said doors-are in closedposition tO fOl'IIl sealed joint. v
